This gym is for the early birds and the late risers, the in shape and the getting into shape. It has an assortment of classes including Kickboxing, Pure Lift, HIIT and Yoga. Classes are offered in the morning, afternoon and after work. Darius and his skilled team take over when class starts, so all you need to do is show up.

Fithouse Denver is a second home for me. Ever since day one, I’ve felt both welcomed & challenged! I had absolutely no kickboxing experience and Dariusz dynamic classes and teaching methods quickly had me addicted to this place. Not to mention, the music is absolutely fire. You get a little bit of everything here, kickboxing, lifts, HIIT & yoga. You won’t miss a beat in your fitness journey when joining the Fithouse family.

I can honestly say this gym is amazing. I’ve been a member since day one and the gym has evolved so much from the beginning. There are a variety of classes that will challenge you but pure lift has quickly become my favorite. The trainers are knowledgeable and encouraging. The community is exceptional and have met so many of my best friends here. Dariusz, the owner, brings fun and fitness to a new level. Give it a try, you’ll be hooked!

Been to three separate classes so far, with three different instructors, and all sessions have been engaging and intense. There’s an emphasis on form and proper movements while keeping workouts difficult. The variety is good and a lot of different movements are incorporated. You get a good balance of strength and mobility.

Besides being the only HIIT, Strength, and Kickboxing gym in Denver WITH infrared saunas, a cold plunge and compression boots….wait do you need me to keep going? The trainers care, simple as that. I’ve been to other HIIT gyms where it seems like instructors are just passing time. Put this at the opposite end of the spectrum. They’re engaged and excited to share the custom workouts they craft every three weeks. It’s simply the best.

After taking some time off fitnessing at a proper gym I can say that coming back to Fithouse has been amazing. It’s great to see both new and familiar faces. The coaches and staff are all super knowledgeable and accommodating. The workout formats are challenging and engaging. Best gym around hands down

This gym is incredible. The coaches, classes, facilities, and people are fantastic. The Pure Lift classes and Mobility with Abbey are my personal favorites because the progress is evident and they support activities that I do in my day to day life. I love having access to a cold plunge, sauna, and stretch room for recovery. I can’t imagine going to any other gym.

This gym is the BEST! I've been a member of Fit House for 2.5 years now. It's the first gym I've stayed at for more than a few months and been consistent with. Each coach is welcoming and knowledgeable and they all offer a unique coaching style. The gym itself is clean and has an awesome selection of equipment. Fit House, its staff, and members have managed to create a non-intimidating atmosphere that pushes you to constantly meet and beat your fitness goals. I love this gym and everyone I've brought has loved it as well :)

I have been regularly attending Pure Lift classes for 7+ months now and I can honestly say it’s my favorite gym I’ve ever been to. Between the incredibly knowledgeable trainers, the non-judgemental and welcoming atmosphere, cold plunge and sauna options, and the plethora of other things Fit House offers, you will not find anything better in the Denver and surrounding areas. Every single coach has an amazing approach to their classes, and you will not be disappointed regardless of who teaches. It is genuinely one of a kind, and I highly recommend to take at least one class. Plan to clear your schedule because you’ll be hooked!

Hands down the best gym in Denver. I spent months trying different gyms around Denver and slowly started coming to more classes at Fit House. After coming more consistently I quickly realized it’s an amazing community of great people with extremely talented coaches. The lift classes are my favorite. Structured hour long classes hitting every muscle group throughout the week. Would recommend

The BEST gym in Denver. Everyone on staff is incredible, especially Alessandro, who truly defines five-star customer service. The workouts are always challenging, and the recovery methods offered in-house will keep your body up to the challenge.

Love love love this place! The workouts push me to lift heavier than I ever have and the instructors are so knowledgable and helpful. Bonus... They always have something new and exciting happening in the gym, which makes for a fun environment! I now look forward to going to workout each and every time!

Fit House is my Fitness sanctuary. The classes are high energy and fun. Workouts are well put together and the people are awesome. The amount I get done in a 1 hour class would take me 2 at any other gym. Come workout with us!

Newbie and had a friend referral. I’ve been actively working out my whole life am an ex Crossfitter/Coach. This gym is so organized and provided such a well rounded workout. Gina was my coach and she had such great energy! Her playlist was 🔥 The owner gave me a tour and he was so thorough and the facility is HUGE insane—literally everything you could ask for, for recovery! Highly recommend this gym for an all encompassing experience from workout—recovery!

Fit house is the best gym in Denver! The instructors are super knowledgeable and the workouts are always killer, especially the pure lift classes! I highly suggest you check them out!

My absolute favorite gym! They offer a variety of classes, lift, kickboxing, and HIIT, which are all challenging and fun! The variety of the classes allows you to never get bored of a workout. The coaches are great! They will push you to your highest potential while also making sure your form is correct. Lastly, the community is unlike any other. Everyone is extremely welcoming and supportive. I love this place!

First off I appreciate how clean it always is, many gyms do not put much effort in tidiness but FitHouse does! The equipment is all in great shape, music bumps, the trainers are so knowledgeable & friendly. The HITT / Kickboxing workouts are straight fire... calories torchers!! The lift classes are well balanced and VERY effective! This place rocks!!

My favorite gym in Denver! The lift classes are my favorite - I’m so much stronger now than I was a few months ago, and more comfortable in a gym setting than I’ve ever been in my life. Also the friendliest and most knowledgeable coaches in town. Dariusz, Abbey, and Stan are incredible 🤌🏼

I love this gym! Fit House has been incredibly welcoming since day 1 and offers an awesome class variety. They have HIIT, lift and boxing classes that are all super challenging and provide a lot of variety! The trainers are also super knowledgeable, they are always there to not only correct your form but cheer you on through all your fitness goals!

The best! Great variety of classes, all of which ensure an amazing workout complete with all the endorphins. The equipment is in excellent condition, and the owners strive to innovate constantly. Not to mention the spa like showers equipped with everything you’d need to get ready after a good sweat. Oh and parking is the easiest! I love it here!

Two years later, I still have nothing but a glowing review for FH! If you're looking for a place to workout, challenge yourself, and belong to a community look no further!! Review from 2021: I highly recommend Fit House if you are looking for a group fitness gym that will provide you with both a social outlet and an amazing physical challenge. Every workout at Fit House is spot on-challenging, great pace, fun, good variety, and will leave you sore the next day. Also, the personal attention given by the instructors to each member during every class is great-they make sure I'm not going to hurt myself doing the moves, and help if you need to modify the moves. They have a great mix of classes too, so you never get bored or are over-working the same muscles. Dariusz is the best, and I have never regretted taking any of his classes and always look forward to coming back :)

I tried their kickboxing class here. Loved the format, and the technique adjustments. The instructor/owner is extremely friendly and knowledgeable. Would strongly suggest this gym.

I've been a member since day 1. This gym is the best in Denver, hands-down & I've tried lots of other gyms. The schedule & signing up helps keep me going every day. They have the most welcoming environment, offer new moves every two weeks, and have tough but do-able workouts (AND I modify with help from all the instructors regularly because I have a bum knee & shoulder). The schedule is balanced with robust class choices. There's something for everyone - kickboxing, lifting, HIIT-style workouts, AND yoga! It's super-clean, has something for everyone, and you'll never be bored with your workout. There's a recovery center next door to help you stay at the top of your game too! Super-convenient to metro Denver and reasonably priced - why aren't you going here yet?!

I can honestly say this is the best class-based gym I’ve been to. Not just in Denver but across the US. The atmosphere is motivating, the coaches are extremely educated and excited to help you progress, and the workouts are killer. True bodybuilding techniques that will make your body change, rather than most classes that have you jumping around a lot just for high heart rate. You will get hooked on this gym!!! Couldn’t recommend it enough.

One of the best gyms in Denver, complete workouts that have a reason behind and no running outside. Dariusz and all the coaches are helpful, kind and will help you achieve your fitness goals and they work any level that you are. I have been training with his team for more than 1 year with consistent and attainable results. Not to mention ALL facilities are modern, well equipped, clean and sanitized. I recommend you come and try it.

I absolutely love Fit House. As a previous class pass user, I would try out different gyms and didn’t really find one that I wanted to stick with until I came to a Fit House class. Every coach is extremely knowledgeable and helpful in getting form right and challenging you to become a better version of yourself. The gym itself is top tier - the staff is so friendly, equipment is well maintained, the facility is clean and has everything you would need. On top of all of that, the members of Fit House are friendly and there’s a strong sense of community. 10/10 recommend checking out Fit House and all they have to offer!

I love Fit House. I attended my first class a little over a year ago while shopping around different gyms in Denver, and immediately afterward I stopped looking and joined - with no regrets. The coaches are extremely knowledgeable, the classes are well thought out and always rotating, and the community is so welcoming and motivating for ALL ability levels. The Fit House family has totally changed my relationship with fitness. I can't recommend Fit House enough!

I love Fit House! Great trainers, top-notch equipment, and strong community focus. The Pure Lift classes (my favorite) are organized and have excellent programming. You can come every day of the week even if you are sore since each class has a different core muscle group focus! Highly recommend Fit House to anyone looking to elevate their fitness game!
